keybase ipc on ios - tips please

Apologies if this is the wrong forum for code questions. Point me in the right direction if you know where..

According to the doco, the keybase service communicates with various UIs over unix domain sockets. I've found the go code, but where is the matching UI code for OSX / IOS? Is it abstracted away through some library?

Start with the Go code and documentation mentioned in the issue, then trace the Unix domain socket interfaces used by the service. Identify where the matching OS X and iOS UI code lives and whether a library abstracts the IPC; the issue is done when those entry points and the relevant abstraction are documented.
